We (once) sent Noah to his people, and he tarried among them a thousand years less fifty: but the Deluge overwhelmed them while they (persisted in) sin. 14 But We saved him and the companions of the ship, and We made it a sign for the worlds. 15 And Abraham, when he said to his people, 'Serve God, and fear Him; that is better for you, did you know. 16 You only worship, other than Allah, idols and invent falsehoods. Those whom you worship, other than Allah, have no power to give you provision. Therefore seek the provision of Allah, and worship Him. Give thanks to Him, to Him you shall return' 17 And if you [people] deny [the message] - already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification. 18 (Have they not seen how God originates creation, then brings it back again? Surely that is an easy matter for God. 19 Say, [O Muhammad], "Travel through the land and observe how He began creation. Then Allah will produce the final creation. Indeed Allah, over all things, is competent." 20 He punishes whom He will, and shows mercy to whom He will, and to Him you will be returned. 21 You are not able to frustrate Him either in the earth or in heaven; and you have not, apart from God, either protector or helper. 22
